Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Progression-free survival (Time from randomization until progression of metastatic disease, or death from any cause). Measuring time: 20 months.

Key secondary outcomes:

Overall Survival (Time from randomization until death, from any cause). Measuring time: 20 months. Antitumor response (RECIST (version 1.1) scale). Measuring time: After completed the third cycle and the sixth cycle of first-line chemotherapy for metastatic disease, and then every 4 months up to 20 months. Immune response variables: IgM and IgG against NGcGM3 ganglioside (ELISA). Measuring time: At baseline, Third (85), Sixth (169), Twelfth (337) days Recognition and lytic capacity of IgM and IgG antibodies induced by vaccination and directed to NGcGM3 on tumor lines expressing ganglioside (flow cytometry). Measuring time: At baseline, Third (85), Sixth (169), Twelfth (337) days Safety variables: Adverse Events (AE). Measuring time: Time of evaluation: every 3 months until 20 months. The AE are defined by - Description of the AE (Name of the AE) - Intensity of the AE (mild, moderate, severe, life-threatening, death) - Causality relationship (very probable, probable, possible, unlikely, not related, not evaluable ) - Gravity (serious, non serious) - Previous knowledge (expected, non expected) - Result (recovered, improved, sequelae, death ) - Treatment (none, medication, surgical procedure, transfusion, other) Quality of life (Questionnaires EORTC QLQ-C30 (cancer), EORTC QLQ-BR23 (breast cancer), and EORTC QLQ-BM22 (patients with bone metastases) . Measuring time: At baseline, and at 6, 9, 15 and 20 months
